We did the shark expedition aboard the Quino El Guardian in November 2019 with shark researcher Mauricio Hoyos Padilla. If I could give 10 stars to the boat and crew I would, in every category. The boat is amazing, it isn't a luxury liveaboard, but has everything you need for an amazing trip. The dive deck and camera tables are more than adequate. The crew was very attentive, fun and safe. Our captain was Julio, safety is his number one priority. He was always available for questions, and kept us very informed on our itinerary based on the weather conditions. Dori and Joshua put out 5-star meals during the entire trip, they worked tirelessly to make sure everyone had a wonderful dining experience. I have food allergies and they were very careful to make sure I got an amazing meal each and every time. There were always plenty of snacks and drinks available.
The divemasters were very professional, Lois and Gabby know how to get the most out of Socorro so you will have an amazing experience.
The rooms on this boat are very small so don't bring a lot of extras. There is a place for you to store your luggage after you unpack so it doesn't have to stay in the room.
The diving in Socorro is second to none if you are looking for pelagics. The mantas made an appearance on every dive, they were so curious and seemed to hang around for the entire dive. We had fun playing with dolphins, swam with huge schools of tiger sharks, the Galapagos, silver tips, silkies, white tip sharks were always present. I don't think we had a dive without all of the above mentioned. We were at the beginning of whale shark season and the last day of the dive a huge pregnant female made an appearance and we dove with her for at least 30 minutes.
I would suggest going early in the season, there were only 3 boats in the area when we were there so the captains coordinated our locations so we were guaranteed to be the only boat at each dive site.
